Labasics Glass Capillary Tubes 100mm 0.5mm ID/0.7mm OD Pack of 1000

Description

Product Overview

Labasics glass capillary tubes are precision‑engineered laboratory tools designed to meet the demanding requirements of thin‑layer chromatography (TLC), micro‑fluidic experiments, and a wide range of analytical procedures. Constructed from high‑quality borosilicate glass, each tube offers exceptional chemical resistance, thermal stability, and optical clarity, ensuring that users can observe fluid movement without distortion. The tubes measure 100 mm in length, providing ample reach for standard TLC plates while maintaining a compact profile that fits easily into most laboratory racks and holders. With an inner diameter of 0.5 mm and an outer diameter of 0.7 mm, the tubes deliver consistent capillary action, allowing precise sample application and reproducible spot sizes across multiple runs. The generous pack of 1,000 units guarantees a reliable inventory for busy research labs, teaching facilities, and quality‑control environments, while the included 1‑year limited manufacturer warranty underscores Labasics’ confidence in product durability.

Each capillary tube is manufactured under strict clean‑room conditions to prevent contamination and to preserve the integrity of the glass surface. The uniform wall thickness and tight diameter tolerance of ±0.1 mm ensure that fluid flow rates remain predictable, reducing variability caused by irregularities. The smooth interior surface minimizes sample adhesion, which is especially important when working with low‑viscosity solvents or delicate biological reagents. The tubes are also compatible with a variety of standard laboratory accessories, such as tube racks, magnetic stirrers, and micro‑pipette adapters, making them a versatile addition to any scientific workflow.

Labasics has incorporated a user‑friendly design that simplifies handling and reduces the risk of breakage. The tapered ends provide a comfortable grip for precise positioning, while the robust glass composition resists chipping during routine use. For laboratories that require sterilization, the tubes can be autoclaved without compromising dimensional stability, allowing for safe reuse in sterile environments. The clear, color‑neutral appearance of the glass also aids in visual inspection, enabling quick detection of bubbles, particulates, or other anomalies that could affect experimental outcomes.

Beyond TLC, these capillary tubes are ideal for applications such as micro‑extraction, sample loading for gas chromatography, and the delivery of reagents in micro‑reaction chambers. Their consistent inner diameter supports accurate volume measurement when used in conjunction with calibrated capillary fillers or micro‑syringes. Researchers have reported improved reproducibility in quantitative assays, as the uniform capillary action reduces the influence of operator technique on final results. The 100 mm length also provides sufficient reach for accessing hard‑to‑reach areas within custom experimental setups.

Packaging is designed for convenience and protection. The tubes are sealed in moisture‑resistant blister packs that prevent exposure to humidity, which could otherwise affect glass surface properties. The bulk pack of 1,000 tubes is organized in a sturdy cardboard box with clear labeling, facilitating inventory management and rapid retrieval. Labasics also provides a downloadable PDF with detailed specifications, handling guidelines, and safety data sheets, ensuring that users have all necessary information at their fingertips.

Quality control is integral to Labasics’ manufacturing process. Every production lot undergoes ISO‑9001 certified inspection, including visual examination for micro‑cracks, dimensional verification with calibrated micrometers, and surface roughness assessment using profilometry. Test samples are also subjected to chemical compatibility trials with a range of solvents to confirm inertness. Documentation of these procedures is provided upon request, giving laboratories confidence that the capillary tubes meet rigorous industry standards.

Usage

These capillary tubes excel in thin‑layer chromatography laboratories where precise sample spotting is critical for achieving sharp, well‑defined bands. By gently touching the tube tip to the TLC plate, users can deposit controlled volumes of analyte, leading to improved resolution and more accurate quantitative analysis. The 0.5 mm inner diameter allows for fine droplets, while the 0.7 mm outer diameter provides enough rigidity to maintain a steady hand during application.

In addition to TLC, the tubes are frequently employed in micro‑extraction protocols where small volumes of liquid must be transferred between phases without loss. Their chemical‑inert glass composition ensures that no leaching or contamination occurs, preserving sample purity. The tubes are also suitable for loading samples into gas chromatography injectors, where the consistent inner diameter helps achieve reproducible injection volumes, contributing to reliable chromatographic peaks.

Educational institutions benefit from the durability and ease of use of Labasics capillary tubes. In teaching labs, students can practice capillary action principles, observe fluid movement, and conduct simple quantitative experiments with confidence that the equipment will not break under normal handling. The clear glass aids in visual learning, allowing instructors to demonstrate concepts such as capillary rise, surface tension, and wetting behavior directly on the tube.

Advanced research applications, such as microfluidic device fabrication and nanomaterial synthesis, benefit from the tubes’ precise geometry. The uniform inner diameter enables controlled flow rates in micro‑reactors, facilitating reproducible reaction conditions at the microscale. Researchers have integrated these capillary tubes into custom flow‑through systems, leveraging their transparency to monitor reaction progress in real time using optical microscopy.

FAQ

What types of solvents can be used with these glass capillary tubes?

The tubes are made from borosilicate glass, which is resistant to most organic solvents, acids, and bases commonly used in laboratory settings. Users can safely work with solvents such as ethanol, methanol, acetonitrile, dichloromethane, and aqueous buffers without concern for glass degradation.

Can the tubes be sterilized for microbiological applications?

Yes, the capillary tubes can be autoclaved at standard conditions (121 °C for 15 minutes). The glass maintains its dimensional stability after repeated sterilization cycles, making the tubes suitable for sterile sample handling and microbiology protocols.

How do I ensure consistent spot size when using the tubes for TLC?

Consistent spot size is achieved by maintaining a steady hand and using the tapered tip to gently touch the TLC plate. It is recommended to pre‑condition the tube tip with a small amount of the solvent system to promote uniform wetting, and to practice on a test plate before applying to critical samples.

Are the tubes compatible with standard capillary fillers or micro‑syringes?

Absolutely. The 0.5 mm inner diameter matches the specifications of most commercial capillary fillers and micro‑syringe adapters, allowing precise volume measurement and transfer. Users can select the appropriate filler size based on the desired volume range for their specific application.
